Are you sure that it is not hardened? Some users have
confused drill ROD with drill BLANKS. Drill blanks are
hardened and can't be turned in the lathe. Drill rod
can also be in a hardened state that can't be turned.
I have cut a number of threads in drill rod without
too much trouble, although, as Roy points out, it is
not the easiest material to work with compared with
brass or aluminum.

All that being said, drill rod is a real bear to
get clean threads
on. Single point roughing followed by a die is a
winning method,
enhanced with a thread file for final finish.

chuck on my Homier 7x12 and cut a 1/4-20 thread, and
could not. The
rod would slip in the chuck, no matter how hard I
tried to crack the
jaws closed. Is that as expected, or do I need to
do something to my
chuck?
